Pavel said the "bcp tool ... errs on safety side" not smart pointers. 
The bcp tool includes any referenced "libraries" from smart_ptr in your 
case. So it may be that:

a. smart_ptr only uses MPL for some compilers but not yours. It doesn't 
distinguish as it doesn't try and decipher the preprocessor code. Just 
that a file has "#include" some other file.

b. It may be that smart_ptr includes only 1 isolated file of another 
library, but it may copy over more than just that file to be safe.
